Specification of Letters Patent.

Patented Nov. 28, 1911.

Application led December 26, 1908. Serial No. 469,346.

To all whom it may concern:

Be it known that I, CESARE FnRocI, civilservice clerk, a subject of theKing of Italy, resident of 17 Piazza Cavour, Rome, Italy, have inventedcertain new and useful Improvements in Elastic-Hub Wheels, of which thefollowing is a specification.

The object of my present invention is to provide an improved elastic hubwheel the main feature of which is the insertion, of a plurality of coilsprings in the intermediate chambers between the hub and inner rim orcrown of the wheel.

Figure l of the annexed drawings shows an elevation of my improvedelastic hub wheel, Fig. 2 an enlarged fragmentary elevation of same,partially sectional and with cover plate partially broken away to showthe interior elastic device, and Fig. 3 a half section on line 3 3 ofFig. 2.

The hub A terminates in chambers B opposite a corresponding number ofchambers C cast integrally with the inner rim D and its iange E. On theinner rim D and its flange E are Xed the spokes F. Flange E of rim D,outer plate Gr and rim D with its chambers C are connected to hub A onlyby perforated rubber pads I and the coil springs H supporting the weightand load of the vehicle.

As is seen from D Fig. 3, in each of the casings formed by chambers Band C, a plurality of coil springs I-I (three in the case hereillustrated) are placed, which are alternated with perforated rubberpads I so that on sudden jerks or jolts due to braking or obstacles thesprings are not overstrained so as to be deformed.

L is an inner flange cast integrally with hub A, and M is an outer coverplate of protection which is screwed in place after the springs H andrubber pads I have been set and the outer flange G screwed home.

Having now fully described my said invention and the manner in which thesame is to be performed, what I claim and desire to secure by LettersPatent of the United States of America is:

l. An elastic hub wheel comprising a hub having radial chambers on itscircumference, an inner rim having radial chambers on its innercircumference, spiral springs having their ends resting in the chambersin said rim and hub, and V-shaped rubber blocks located between theadjacent springs and having their ends resting in the chambers in therim and hub.

2. An elastic hub wheel comprising a hub having radial chambers on itscircumference, certain of said chambers being provided with parallelwalls and the rest of said chambers being provided with walls convergingtoward said hub, said second mentioned chambers being positioned inalternate relation with first mentioned chambers, an inner rim havingradial chambers on its inner circumference, certain of said chambersbeing provided with parallel walls and being positioned opposite theiirst mentioned chambers on the hub, and the rest of the chambers insaid rim being provided with walls converging toward said hub and beingpositioned opposite the second mentioned chambers on said hub, spiralsprings interposed between said hub and said rim and having their endsresting in the chambers provided with parallel walls, and V-shapedrubber blocks interposed between said hub and said rim and having theirnarrow and wide ends resting in the chambers provided with convergingwalls in the hub and rim respectively.

In testimony whereof I have affixed my signature in presence of twowitnesses.

CESARE FEROCI.
